At what age do they get the chicken pox vaccine?  We lived in Ohio when my son was between ages 1 and 4.  I know he got the vaccine and hasn’t gotten chicken pox. He hasn’t been thru an epidemic though.  I’m surprised that if all the kids got the vaccine they’re still getting it.  Supposedly they’ve been using it in Japan for 50 years or something like that and it’s been good there.
